'To all whomz't. mayconcern:

Be it known that 1, CHARLES A. RUMBLE, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Air-Treating Machines; and I hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, forming part of this specification.

This invention relates to improvements in machines, whereby air passing through said machines may be supplied with moisture. I

'Oue object of the inventionis to improve the construction of the means for sustaining themoisture.

Another object of the invention is to improve the construction of machines of this nature with respect to the water tank which forms a drip receptacle, and in the means-for driving the air drawing fan shaft.

Other objects of the invention will appear from the following description.

Figure 1, represents a front view of the improved machine shown partially in section. Fig. 2, represents a section taken on line 2-2 Fig. l,looking downward. Fig. 3, represents a similar view taken on line 33 Fig. 1'.

' ing arts throughout Similar numbers, of reference designate correspond- As shown in the drawings, in its preferred form, the

machine comprises a cylindrical casing 5'havingat its lower end the annular. guides 6-6 and the openings 77 between said guides and furnished with the ring 8 having the opening 9-9 and knob 10,,which ring is free to slide in the guides 6-6 of the casing 5, whereby the ring 8 may be rotated, about said casing, to bring the. opepings 99 opposite those marked 77, to v 35" admit air to the machine, when desired or to bring parts of said ring 8 over said openings 77 to close said openings when itis desired to draw air from the upper part of the machine. The upper portion of the casing has an air inletpipe; connected with'any, preferably exterior, air supply.,

Within the casing 5 are mounted the frames 11 and 12, secured to the casing, 'and on the frame 11 is mounted the fan chamber 13 having theoutlets 14.14 which extend through openings in the wall of the casing 5. From the frame 11 extends aseriesof bolts 15-15, nuts l616 on which, assist in supporting the frame 12, the

casing 17 and the spirally wound sheet metal moisture delivery plate 18.

Journaled in a bearing in the frame 11 is the fan shaft 19,whicl1 is supported on the ball bearing 20 and is furnished at its upper end with the fan 21 and at its lower end with the bevel gear 22 which is protected by the gear casing 23 from which the tube 24 extends upward to the frame 11. The gear22 is driven from the bevel gear 25 mounted, on the shaft 26 which .isjoure' tween the wet surfaces of the spiral plate-18.

naled in bearings carried respectively by the gear cas- 7 ing 23 and by the water tank, the outer end of saidshaft having the pulley 27'which may be driven in any usual manner.

On the lower. ends of thebolts, or rods, 15.15 and-se-' cured thereon by the nuts 15-15, is mounted'the tank 28'having the annular flange 29 which receives the lower end of the casing 5. In the center of this tank is the pedestal 30 having the tubular bearing 31, the pump casing 32 and the gear casing 33 which latter is designed to be secured to the casing23; Within the bearing 31 is journaled the shaft 34 having at its upper end the bevelgear 35, meshing with the gear-25, and

at its lower end the rotary pump 36 within the casing from said, tank may pass through the overflow pipe 45. v

The shape of the moisture distributing plate 18 will be understood by reference to Fig. 2 of the drawings from which it will appear that said plate is wound upon itself and that the spaces between the convolutions are spiral in cross section. By this construction the moisture supporting element can be economically constructed and its several convolutions are accurately spaced.

With the ring moved to a position to close the openings 77 in the casing 5, and with a supply of water, or water mixed with steam, in the tank 28, the pulley 27 is driven and thepump isoperated to draw water from the tank and force the same to the sprayer 39 from whence it is delivered in fine streams, or spray, tothe upper end of the spiral sheet 18; at the same time the fan 21 is driven and draws the air from thelowerportion of the casing 5 up through the casing 17, this supply of air'being continually renewed by air passing into the casing 5 through the inlet at the upper end of said casingb. As theair passes upward between the wet surfaces of the plate 18 a large proportion of the moisture on said surfaces is absorbed by the air and, as the.

casing 5, to bring the openings in said ring in registra tion with the openings 77'of said casing, wh er'eupon the flow of air is through said openings directly intothe 1 lower end of the inner casing 17 and thence upward be- It; is to be noted that the tank 28 is readily removable from the casing 5 as the securing means or the gear cases and other inner parts are accessible through the 0pening'77 of-said casing 5 and the-nuts 15.l 5 of the supporting bolts 15-15 are outside said casing.

Having thus described my invention I claim as new and desire to secure by Letters Patent.

1. An air treating machine comprising an exterior casing having an air inlet at the top, an inner casing haying air outlets at its upper portion. a moisture distributing element located within said inner casing. means for supplying water to the upper end of said element, a tan rotatably mounted above said element, and means for rotating said t'an.

2. An air treating machine comprising an exterior casin having an air inlet at the top, an: inner casing, havint, air outlets at its upper portion, a moisture distributing element within said inner easing. means for supper-tin; said inner casing and said element, consisting of a series of bolts, and a tank secured to the lower ends of said bolts,

tainin; said element, a tank secured to the lower portions of said bolts a rotary pump located within said tanlt. a spraying device located above the distributing element. pipe connecting Said p ayinn'deviee with said pump. a fan rotatably mounted at the upper portion of the inner casing and haying a shaft extendinf: downward therefrom. and means for simultaneously driving the pump and the fan shaft as described.

In testimony whereof I atlix my signature in presence of two witness s.
